Grapevine plant named &#39;14-48-258&#39;

ABSTRACT

This new seeded variety of table grapevine ‘14-48-258’ is new and different because of its firm texture, uniform clusters and large berry size. Its clusters are well-filled, but loose; its large berries are sweet and mild. The vigorously growing vines are extremely productive when spur pruned.

GENUS AND SPECIES

[0001]Vitis vinifera

BACKGROUND AND SUMMARY OF THE INVENTION

[0002] The new table grapevine cultivar ‘14-48-258’ is of Vitis vinifera parentage. The goal in the development of this new table grape was to provide an alternative to the widely grown cultivar ‘Alphonse Lavalle’ (unpatented).

[0003] The seeded, female parent of the new variety is an un-named black table grape of uncertain parentage with large berry size and high fruitfulness. The seedless, male parent of the new cultivar is the variety ‘Fantasy Seedless’ (unpatented). The hybridization resulting in the new cultivar was made in 1993 near Delano, Calif. Seed from the cross was harvested, stratified and sown in a greenhouse in January 1994. The resulting 47 seedlings were planted in a field in the same area in March of the same year. In 1997, fruit was seen on the vine for the first time and it was selected for further trial. Vines were propagated from the original seedling in the spring of 1998 with own-rooted and grafted vines planted in the original trial. Those vines and subsequent propagules have all been true to type.

COMPARISON WITH PARENTAL CULTIVAR

[0004] The new cultivar differs from its ancestor, ‘Alphonse Lavalle’ by having a much more well-filled cluster. The berries of ‘14-48-258’ are about 2 g. larger than ‘Alphonse Lavalle’ on average and have flesh which is firmer than that of the latter cultivar. Additionally, the berry shape of ‘14-48-258’ is generally elliptic to obovate with clearly defined lobing on the stigmatic end of the berry, whereas ‘Alphonse Lavalle’ has nearly spherical berries.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

[0007] The following description of grapevine ‘14-48-258’ contains references to color names taken from the Munsell Color Chart for Plant Tissues, published by Munsell Color, New Windsor, N.Y. Descriptors used herein conform to those set forth by the International Board for Plant Genetic Resources Institute Grape Descriptors (Vitis spp.) of 1983 and/or 1997 which were developed in collaboration with the Office International de la Vigne et du Vin (OIV) and the International Union for the Protection of New Varieties of Plants (UPOV).

[0008] Descriptions of the new invention apply to vines of ‘14-48-258’ grown on ‘Freedom’ rootstock at a density of 1,537 vines per hectare grown in Kern County, California in 2001.
